Born a legend. Back to Raise Hell.
Some bikes make history. Others rewrite it. In 1988 and 1989, Willie G. Davidson rode early Fat Boy® prototypes into Daytona, seeking direct feedback from riders and igniting a legacy that would span generations. By 1990, the Fat Boy was born, quickly becoming one of the most legendary models in Harley-Davidson history. Now, 35 years later, the new 2025 Fat Boy® Gray Ghost charges forward, bringing that legacy full circle. Inspired by the riders who made it an icon, this tribute honors the past while the next generation keeps the fire burning.
ICONS COLLECTION | 2025 FAT BOY® GRAY GHOST
THEN. NOW. FOREVER.
A bike built to make a statement, the Fat Boy® Gray Ghost returns to
honor its past and inspire the future.
Design
The original Fat Boy® set the standard, and the all-new 2025 Fat Boy® Gray Ghost takes it further. Its legendary silver and yellow color scheme returns, now with a stunning mirror-like finish created through an advanced Physical Vapor Deposition (PVD) process, plus full LED lighting for a bold, modern edge.
Performance
The Fat Boy® Gray Ghost blends classic style with modern power. The Milwaukee-Eight® 117 Custom V-Twin Engine and timeless round air cleaner give it the perfect mix of muscle and attitude.
Innovation
All the benefits of Rider Safety Enhancements and Ride Modes are hidden in classic cruiser form and managed with intuitive, ergonomic hand controls.
Rider Safety Enhancements
Harley-Davidson’s Rider Safety Enhancements is all about giving you that extra peace of mind when things get a little unpredictable. It’s a set of smart tech that steps in during tricky situations, helping the bike handle traction while you are accelerating, braking, or slowing down. With the Corner Rider Safety Enhancements, the bike even adjusts for cornering, keeping things smooth and steady without you having to think twice.
Anti-Lock Brake System (ABS)
An anti-lock braking system, or ABS for short, is designed to help prevent skidding when you brake. It keeps wheels from locking up during braking so you can maintain traction with the road surface. With a series of speed sensors, valves, and pumps, it can rapidly “pump” the brakes up to 15 times per second.
Drag-torque Slip Control System (DSCS)
DSCS is designed to reduce excessive rear-wheel slip and help prevent rear-wheel lock under powertrain-induced deceleration, which typically occurs when the rider makes an abrupt down-shift gear change or quickly reduces the throttle while on wet or slippery road surfaces.
Traction Control System (TCS)
The TCS is designed to keep the rear wheel from “spinning out” when the motorcycle is accelerating in a straight line and enhances rider confidence.
Tire Pressure Monitoring System (TPMS)
TPMS alerts the rider through the information display to low or high tire air pressure. Maintaining proper tire air pressure is important both for vehicle performance and tire life.
2025 FAT BOY®
Adored since day one, the singular Fat Boy stands out with bright chrome and bold finishes, and now it is better than ever with a big Milwaukee-Eight® 117 Custom V-twin engine.
Fat Boy® Through the Years
Take a ride through 35 years of bold design and legacy shaped by riders. From its 1990 debut to its return in the 2025 Fat Boy Gray Ghost, see how it became one of the most iconic motorcycles of all time.
